PIC18F46K80-I/ML 概要
A microcontroller (MCU) is a single-chip computer containing a CPU, program memory, data memory, and programmable I/O peripherals. The PIC18F46K80 belongs to Microchip's PIC18 XLP family, which sits within the broader 8-bit PIC microcontroller hierarchy (PIC10/12/14/16/18). It is engineered for low-power embedded applications with high analog precision and a robust CAN interface.
Key features include 64 KB Flash program memory (32K x 16), 1 KB EEPROM, 4 KB RAM, 12-bit ADC with up to 11 channels, 2 analog comparators, 2 CCP/ECCP modules, an integrated ECAN module compliant with CAN 2.0B, 2 MSSP (SPI/I2C), 2 enhanced USART, and a Charge Time Measurement Unit (CTMU). The 44-QFN package provides a compact 8x8 mm footprint with an exposed pad for thermal dissipation.
Architecturally, the device uses an enhanced Harvard RISC core with a 16-bit instruction word and 8-bit data path, achieving 16 MIPS at 64 MHz. The nanoWatt XLP technology offers sleep currents as low as 20 nA typical, while the integrated ECAN controller supports up to 1 Mbps bus speeds with hardware filtering. The 12-bit ADC delivers up to 100 ksps with acquisition-plus-conversion timing controlled by the CTMU.
Typical applications include automotive body and HVAC control, building automation nodes (BACnet/Modbus bridges), elevator controller boards, industrial sensor nodes with CAN backbone, and battery-powered metering. The wide 1.8 V to 5.5 V range and XLP modes support direct Li-Ion battery operation.
When designing with this part, ensure proper decoupling on VDD/AVDD pairs, route the ECAN TX/RX lines as a differential pair with 120-ohm termination, and follow Microchip's recommended QFN thermal pad soldering pattern (NSMD land, 9 thermal vias). Programming/debugging uses ICSP over the standard PGC/PGD/PGM lines via PICkit or MPLAB ICD.
This page synthesizes distributor pricing, drop-in QFN-44 alternatives, and practical design notes not found in the standalone Microchip datasheet, helping engineers compare MCUs and source reliably.

主な用途
PIC18F46K80-I/ML の用途: 6 件s: Automotive Body and HVAC Control, Building Automation and BACnet Nodes, Elevator Control Boards, Industrial Sensor Nodes with CAN Backbone, Battery-Powered Metering and Telemetry, Touch-Key and Capacitive Sensing Panels.
Automotive Body and HVAC Control
The PIC18F46K80-I/ML fits automotive body controllers and HVAC modules because of its integrated ECAN 2.0B controller (up to 1 Mbps) and 1.8 V to 5.5 V supply tolerance. With 64 KB Flash and 4 KB RAM it can host CANopen or J1939 stacks alongside HVAC control logic. The CTMU enables touch-key and capacitive sensing for climate-control panels, and the 12-bit ADC supports multiple analog sensor inputs for cabin temperature and pressure.
おすすめ
Building Automation and BACnet Nodes
The PIC18F46K80-I/ML suits building automation controllers (HVAC, lighting, access) because of its low sleep current (XLP), 64 KB Flash for BACnet/Modbus stacks, and dual USART for RS-485 trunks. The 44-QFN package fits inside compact wall-sensor enclosures, and the 2 MSSP ports support SPI sensors plus I2C IO expanders for keypad/LED control.
おすすめ
Elevator Control Boards
The PIC18F46K80-I/ML supports elevator door controllers and floor-node displays because of its ECCP/PWM peripherals for motor control and the 12-bit ADC for current sensing. ECAN links cars to the shaft controller via CANopen DS417, and the 1.8-5.5 V range accepts 24 V industrial rails after regulation. The 64 KB Flash fits full CANopen plus safety logic stacks.
おすすめ
Industrial Sensor Nodes with CAN Backbone
The PIC18F46K80-I/ML serves as an industrial sensor node because its ECAN 2.0B controller, 12-bit ADC, and CTMU enable precision analog measurement plus deterministic CAN communication on the factory backbone. The 64 KB Flash fits CANopen or DeviceNet slave stacks, while the 4 KB RAM buffers measurement bursts. XLP sleep modes extend battery life on remote wireless bridges.
おすすめ
Battery-Powered Metering and Telemetry
The PIC18F46K80-I/ML supports battery-powered metering because of its nanoWatt XLP modes (sub-100 nA typical sleep) and 1.8 V operation directly from a single Li-Ion or 2xAA cell. The 12-bit ADC with CTMU accurately measures voltage, current, and temperature, while the ECAN interface links the meter to a concentrator over CAN. 64 KB Flash fits metering firmware plus secure OTA bootloader space.
おすすめ
Touch-Key and Capacitive Sensing Panels
The PIC18F46K80-I/ML drives capacitive touch panels because its on-chip CTMU provides constant-current charge timing for sliders and buttons, while the 12-bit ADC reads the analog touch waveform. The 64 KB Flash fits Microchip's mTouch library plus the application UI, and the 44-QFN package fits behind thin glass panels. ECAN connectivity allows touch events to be reported over the body network.

主な差別化要因

- On-chip CTMU for capacitive touch and precise timing （vs PIC18F46K42-I/ML)
- Wider 1.8 V to 5.5 V VDD vs K40/K42 family range （vs PIC18F46K40-I/ML)
設計ノート
Place 100 nF decoupling capacitors on every VDD/VSS pair and a bulk 10 uF tantalum near the ICSP VDD pin. The PIC18F46K80's XLP sleep modes draw under 100 nA typical, so the decoupling network must be low-leakage ceramic (X7R) to avoid offsetting the sleep current budget. For ECAN-active nodes, add a ferrite bead between the digital 3.3 V rail and the analog AVDD rail.
The 44-QFN exposed pad (EP) must be soldered to a grounded copper pour with at least 9 thermal vias (0.3 mm drill, 0.5 mm pitch) for heat dissipation. A non-soldered EP can raise junction temperature by 20-30 C at 64 MHz full-load operation, leading to thermal shutdown or ADC drift. Follow Microchip AN246 QFN soldering guidelines for the NSMD land pattern.
Route the ECAN CANTX/CANRX traces as a 120-ohm differential pair with controlled impedance; keep pair length matched within 5 mm and avoid vias on each leg. Place the MCP2562 (or compatible) CAN transceiver within 25 mm of the IC. The ICSP PGC/PGD traces must be less than 100 mm to ensure reliable in-circuit programming with PICkit 4 or ICD 4.
Do not confuse the -I/ML industrial grade (-40 C to +85 C) with the -E/ML extended grade (-40 C to +125 C); the -E variant is required for underhood automotive nodes. Also avoid pulling MCLR low during ECAN traffic - the ECAN module loses bus synchronization if MCLR is held in reset for more than the oscillator start-up time (typ 4 ms).
コンプライアンス情報
RoHS and REACH compliant per Microchip product page. AEC-Q100 qualification not listed for the -I/ML grade; the -E/ML extended temp variant is typically used for underhood automotive. Lead-free and halogen-free per Microchip environmental compliance statements.
